Query for records that have more than N values in a multi-valued field

[Alexandre Rafalovitch <ar...@gmail.com>]

Hello,

I have a multivalued field and I want to find records that have (for
example) at least 3 values in that list. Is there an easy way to do
it?

Regards,
   Alex.

Typically this is solved by adding another field that contains the count 
-- I thought i had already written an update processor in Solr 4.0.0-ALPHA 
that would do this, but aparently i didn't, so i'll add one in SOLR-3670
